Anyone heard of this? I've got some rep hounding me about some new product that are stem cells derived from placenta's that I could utilize in my "pain blocks" according to them. I guess these could potentially be injected epidurally or intradiscally. Don't think there is anyway in hell I'd do this, but anyone hear of it? My initial google search for this lead me to the website for Laser Spine Institute, so I'm probably already permanently biased AGAINST it.
